2.2.2 To connect ATC temperature sensor:
For Automatic Temperature Compensated (ATC) Conductivity readings, an in-built
temperature sensor is usually integrated in the industrial conductivity electrodes.
Otherwise, a separate 100Ω Pt RTD temperature probe can be used.
3 wire temperature sensor
1. Insert the Pt100 input wire to pin 5 of SL1 connector. Tighten the screw.
2. Insert the Pt100 sense wire to pin 6 of SL1 connector. Tighten the screw.
3. Insert the Pt100 return wire and the shield wire to pin 7 of SL1 connector.
Tighten the screw.
2 wire temperature sensor
1. Take a small length of wire and short pins 5 and 6 of SL1 connector. Insert
Pt 100 sense wire into pin 6 of SL1 connector and tighten the screws.
2. Insert Pt 100 return wire and the shield wire to pin 7 of SL1 connector.
Tighten the screw.
IMPORTANT: It is necessary to connect the SHIELD wire to the pin 7 as stated
above to eliminate possible oscillation of the conductivity and/or temperature
reading due to electrical noise or interference.
Ensure that no bare wires are exposed and all screws are tightened for proper
contact.
